Compiling with DMD, with -betterC

DMD64 D Compiler v2.094.2-336-g97aa2ae5e

// works
int f_1(int a){
    enum int[]foo = [1,2,3];
    if(__ctfe)
        return foo[1];
    return 1;
}

// works
int f_2(int a){
    static immutable int[] foo = [1,2,3];
    if(__ctfe)
        return foo[a];
    return 2;
}
// fails with TypeInfo cannot be used with -betterC
int f_3(int a){
    enum int[]foo = [1,2,3];
    if(__ctfe)
        return foo[a]; // Error is reported at this line.
    return 3;
}

All three work with ldc.
